The spring motor constituting the driving means for the shaft is so connected to the latter that the shaft may be operated in either direction and the speed of the shaft automatically regulated or manually retarded or stopped. A movable hood or illustrated in Figs. 7 95- 199; Fig..23, is aviewofjthe brush 189, and the channel 194, and shows 9'0 ready to take its'posi- 1 connected to said brush. The brush is removable from the shaft and may be replaced fender partly surrounds the brush and this fender may be moved independently of the brush. The brush may be given an angular movement, as well as the rotary'and reciprocatory movements. Within the handle of the brush is the container for a solid substance, and mechanism is provided for scraping, cutting or detaching particles from said substance and conveying them to the brush. The nature of the substance will depend largely upon the use to which the brush is put. For instance, if the brush. is employed for polishing purposes, an abrasivepowder may be delivered, and if the brush is employed for cleaning or lathering, a soap or other detergent may be'employed.

-More in detail, the device includes a casing having an enlarged end inclosed by a cap 21. The cap is rotatable in respect to the casing and is movable longitudinally relatively thereto, said longitudinal movement being limited by the engagement of a flange 22 on the cap with a shoulder 23 on the casing, and by the engagement of the end plate 24 of the cap with the outer end of the casing. The end plate 24 has an annular cylindrical flange 25 upon the inner surface thereof and inclosing a helical spring 26.- The outer end of the spring is secured to the inner surface of this flange while the inner end is secured to a sleeve 27 within the casing. This sleeve rotates upon an inner sleeve 28, which latter rotates upon a third sleeve 29. The sleeve 27 has an internal gear 30 and an external gear 31 mounted in parallel planes and of such diameter that a pinion 32 may engage with the internal gear 30 or may engage with the gear 31. The sleeve 27 and its gears 30 and 31 are positively driven by the spring, and thus they rotate the pinion 32 in either direction.

Within the enlarged end 'of thecasing there are two transverse partitions 33 and 34 subdividing the casing into three compartments. The spring and the sleeve 27 and its gears are in the outermost or end compartment, and the arbor 35 upon which the pinion 32 is mounted, extends through the middle compartment and is supported by both partitions. The sleeve 28 extends through the partition 34 and is provided with a gear 36 and a pinion 37, both in the center compartment. The pinion 37 engageswith a gear 38 0n the arbor 35, while the gear 36 engages with a pinion 39 on an arbor 40 supported by the two partitions. On this. arbpr there is also a gear wheel 41 engaging with a pinion 42 on the third or innermost sleeve 29. In the third compartment and mounted on the innermost sleeve 29 is a hub 43 having outwardly-extending spokes 44. Loosely mounted on the spokes are semi-circular weights 45 movable radially and normally held against the hub by suitable springs encircling the.

messes spokes. Both the hub 43 and the pinion 42 a cam 50, which may be engaged by one or both of the weights 45 when the latter are moved outwardly to the limiting extent. On the opposite side of the partition a double pawl 51 is mounted on the shaft 49 and has engagement with an escapement wheel 52 mounted on the shaft or arbor 35. The double pawl 51 is normally held in an intermediate or inoperative position by suitable springs 53, but if the hub 43 and centrifugal weights 45 rotate at too high a speed, they will contact with the cam and turn the shaft 49, so as to bring the double pawl into engagement with the escapement wheel 52.

The outer surface 'of' the cylindrical flange 25 is provided with a peripheral row of teeth 54 shown particularly in Fig. 8, and the inner surface of the end ofthe casing is provided with an inwardly-directed spring 55 adapted to engage with these teeth. Thus, during the winding of the spring, the cap or casing 21 may be rotated in respect to the casing 20 in one direction, but cannot rotate in the reverse direction.

The parts so far described in detail involve the special motor which I preferably employ for driving the operating parts of my improved device. The spring when wound up tends to rotate the sleeve 27, Which latter causes the pinion 32 to rotate. The direction of rotation of the pinion 32 depends upon whether it engages with the gear 30 or with the gear 31. The cap 21, together with the spring and the sleeve 27 are movable longitudinally, so as to bring either gear into mesh with the pinion. As

shown, the pinion is in mesh with the gear 30, but by moving the cap toward the right until the flange 22 is adjacent the shoulder 23, the pinion 32 will be brought into engagement with the gear 31. For retaining the cap in its adjusted position, the casing may have two outwardly-extending projections 56 and 57, either of which may engage in an annular groove in theinner surface of the device. Extending through the body of the casing isa sleeve 58 exteriorly threaded and having a. wheel or end plate 59 threaded thereon. This plate is rotatable in respect to :the casing .20 and its movement along the sleeve 58 toward the motor is limited by a locknut 60 carried by the sleeve and movable along the latter. The plate 59 and the lock nut 60 provide a certain amount of lost movement by means of a projection 59", which permits one tomove through a part of a revolution in respect to the other.

The projection, together with. its correspond ing part on the lock nut 60, constitute a one-tooth clutch. The sleeve 29 extends into the end of the sleeve 58 and is'so. connected thereto that the motor may rotate the sleeve 58in either direction, and after the motor stops the sleeve 58 may continue rotating. To accomplish this, the sleeve 29, which is positively rotated by the motor, 'is provided with two peripheral dogs i6 facing in opposite directions and adapted to swing outwardly into engagement with ratchet teeth upon the inner surface of the sleeve 58.

- There are two rows of these-teeth4c7 and 4:8,

spaced apart a greater distance than the distance between the dogs. The two sets of teeth face in opposite directions and the relative arrangement of the teeth and dogs is such that with the parts in the position shown in Fig. 1, one of the dogs will engage with the teeth 48 and the sleeve 58 will be p sitively rotated by thesleeve 29. Should the sleeve 29 stop rotating, the sleeve 58 may continue rotating, as the dog will slip past the teeth in one direction.

Toreverse the motor the cap 21 is moved longitudinally in respect previously set forth, and this longitudinal movement moves the sleeve 29 also longitudi nally in respect to the casing and brings one dog out of the plane of the teeth 47 and brings the other dog into the plane of the teeth 48. Now, the sleeve 29 rotating in the reverse direction, will rotate the sleeve 58, but should the motor stop the sleeve can 'con-" tinue rotating.

The threads on the sleeve 58 terminate at a short distance from the end of the sleeve remote from the motor, so as to leave a smallbearing portion 61. Mounted on this bearing portion is an end plate 62 having an annular chamber 63 and a plurality of radially-disposed knives or cutters 64:. Adjacent each cutter there is a. passage into the inner chamber for the material shaved off by the cutters, and the cutters are so disposed as to operate on the end of an annular sleeve or to the casing 20, as

threaded engagement tube 65 of the material to be delivered to the brush.

If the device is to be used for cleaningv or as a shaving brush, the annular bar or sleeve 65 would be of soap. The particular character of the material will, of course, depend 'upon the nature of the work to be done by The material 65, which will the device.- hereinafter be referred to as soap, is secured to the endplate 59, so that it cannot rotate with respect to the plate but will be slowly advanced endwise against the cutters 64. The material removed from the bar by casing and terminating in a button 72, but

may be operated automatically by an extra K pressure against the end of the brush. By' the longitudinal movement of the clutch collar 69 it comes into or out ofoperative engagement with the clutch collar 70 and the cutters may be locked against rotation or permitted to freely rotate with the material 65. A

The end of the casing carries an outwardly-extending sleeve formed of two telescoping sections 73 and 74, the former of which is'rigid with the end of the casing. The sleeve 68 extends through the sleeve section 73 and into the sleeve section 74, and

I has rotatably mounted-therein, a screw conveyer 75. This conveyer terminates in a delivery tube 76 extending outwardly through the sleeve section 74 and carrying at its outer end a brush. Atits inner end the conveyer is connected to a rod 77, which latter extends through a partition 78 in the sleeve 58. The rod is held against rotation in respectto the partition, but is free to move longitudinally thereof and the partition is rigid in respect to the sleeve, so that the conveyer is rotated with the sleeve 58. The rod terminates in a slip clutch 79 disposed within a sleeve 80.

.T he end of the sleeve 80 constitutes a second slip clutch 81 and the sleeve 80 is held against rotation so that when the two clutch members 79 and 81 are in engagement with each other, the rotation of the conveyer will cause said conveyer and a brush connected thereto to reciprocate. For bringing the collars into or out of operative engagement, the sleeve 80 has a rod 82 extending through the sleeve 29 to the exterior of the cap 21 and terminating in a ring 83. The rod has with the end of the cap, so that by rotating the rod,'it may be moved longitudinally into or out of position.

The rod 77 has a spring 77 normally inac the but becoming active when the slip clutches 79, and. 81 are in engagement with each other. A flange 84 on the conveyer closes the end of the sleeve .68 and also forms a stop for the spring.

The delivery tube 76 is providedwith a ead 85 inclosed by a casing 86. The casing has a limited longitudinal movement in main stationary during the rotation of the delivery tube 76'and its head. The casing terminates in a. socket 89, within which is disposed a ball 90 carrying the brush 91. The socket and the ball have passages therethrough adapted to register and to convey the material from the delivery tube to the brush. The ball and socket connections are such that the brush although fitting sufii ciently friction tight to rotate with the head, yet may oscillate to a limited extent.

Encircling the head and brush is a guard I 92 supported by the sleeve section 7 1. This guard serves not only to protect the brush but also operates for stopping and starting the rotation of the latter. The casing 86 has upon its rear surface, a series of clutch teeth 93, which may engage with a clutch collar 94 constituting the end of the sleeve section 7 4. The sleeve section 74 is provided with a pin 95 extending out through the slot in the sleeve section 73 and adapted to be held against longitudinal movement in any one of a series of notches 7 3 along the side of said slot. tends to press the sleeve section 741 outwardly so as to bring the clutch members 93 and 9& into engagement with each other.

With the clutch members 93 and 94in engagement with each other, the brush is locked against rotation and the operation of the entire device is stopped. When the guard 92 is pressed upon, the section 7 1 is retracted, compressing the spring 96 and releasing the teeth on the clutch member 94:

from the teeth .on the clutch member 93.

. The clutch member 93 and parts connected therewith are normally held in'forward position by the coil spring 77* (see Fig. 1). By moving the sleeve section74: to the position indicated in Fig. 1, the brush is liberated and permitted to rotate.- The outer end of the guard 92 may be interiorly threaded so as to receive any suitable form of screen or sifting plate 92 (see Fig. 7 to prevent the brush from coming into direct contact with the surface to be treated.

By means of the button 95 the clutch 94 may be brought back to such a position that it will not be engaged by the clutch 93 to stop the brush, unless considerable pressure be applied to the latter. The tensions of the several springs are such that if considerable pressure he applied to the brush, all of the springs will be compressed and the sleeve 68 will be moved longitudinally until the clutch collars 69 and 70 engage with each other to lock the cutters against rotation. The tube or sleeve 65 of the material is non rotatable in respect to the plate 59, but the latter is rotatable with the sleeve 58. The cutter operates substantially in the following manner: Upon starting the motor, the

inertia of the material and heavy plate 59 A coil spring 96 normally tends to unscrew the plate in respect to the lock nut 60, until the two engage and the material is compelled to rotate. When the motor is' stopped more or less suddenly, the momentum of the material causes it to continuerotating in respect to the cutter which may be locked stationary. This rotation of the material and its advancement along the threads of the sleeve 58, cause particles to be removed by the cutter, which may be locked stationary by the clutch collar 69. During the uniform running of the device,

the material, the plate 59 and the cutters,

rotate with the sleeve 58 and there is no advancement of the material or any cutting action.

Instead of using a solid material with a cutter for subdividing the same, I may employ a material in a liquid, semi-liquid or pasty form,"'a'nd avoid a great deal of the complication and details of the form above described.

In Figs. 9 to 14, inclusive, I have illustrated a form in which the material is held in a collapsible container and automatically fed to the brush through the hollow shaft of the latter. Substantially the same motor may beemployed as that illustrated in Fig. 1, and the motor may be controlled in the same manner, although adifferent motor may be employed, if desired. The device includes a casing 100 and a cap 101 rotatable in respect thereto to wind the spring and longitudinally movable to control the direction of rotation. The spring and speed-changing gears are not shown, but motion is transmitted to a centrally disposed shaft 102, which is supported in a outer casing 100 but is rotatable in respect thereto by reason of its engagement with the shaft 102.

At the end of the device remote from the 'motor, the inner casing 105 has a conical end 106 terminating in a delivery conduit 107.

, ably polygonal in cross vided with a plurality Within the inner casing 105 is a collapsible container 108 having end walls 109 fitting the interior of the inner casing and held against rotation in respect thereto. The inner surface of the inner casing is prefersection and is proof circumferential grooves or creases. One end wall of the collapsible container 108 has a conical delivery nozzle 110 within the conical end 106 of the inner casing, so that upon collapsing the container the material will be forced out curved arms 1 or creased inner surface of casing to partially collapse the latter and straighten the arms.

therefore upon the rapid rotation of the casing and container the weights tend to the roughened the casing, the straightening of the arms presses the ad acent ends of the container lengthwise of the the weighted arms engage in eject some of the contents thereof. When the motor is stopped, the weighted arms again become curved and their outer ends enter creases or grooves inthe casing more remote from the motor. In the meantime,

the vother arms prevent. the return of the container.

The outer casing 100 terminates in a tubular extension 113 into which the conduit 107 extends. The conduit is connected by a tight fitting ball and socket joint 114 to a conduit 115 which carries a brush 116 at its outer end. Within the hub 'of the brush there are radially-disposed passages whereby the material delivered through the conduit 115 may pass out through into the brush, and the casing 113 carries a guard 117 inclosing a portion. of the brush to protect the latter and to partially support the outer or free end of the conduit 115. The end of the conduit 115 beyond the brush may be closed by a plug or the like.

For automatlcally stopping and starting the motor, I provide mechanism including two levers 118, each pivoted intermediate its ends to the inner surface of the casing 113 and having at one end a collar 119 encircling the conduit 115 adjacent the brush. Thev conduit or hollow shaftmay freely rotate within thiscollaf, but upon moving about "the joint 114 as a center, the levers are caused to moveupon their joints. -The conduit 107 has a portion 120 adjacent the As the outer ends of gear 174 which may socket end,-square in cross section, and the two arms carry a U-shaped yoke 121, which when in engagement with the square portion prevent the conduit or hollow haft 107 from rotating. QAspring 122 engages with the conduit 115, so as to normally hold the latter with the yoke in engagement with the.

square portion and to lock themotor and brush against rotatlon. As soon as the brush is applied to a surface to clean the latter, the pressure lifts the brush into the'guard 117 against the action of the spring 122,- so as to lower the yoke 121 into inoperative position and perm t the starting of the motor.

In case it is desired to deliver'the material to the brush in tablet form, I preferably em- P y Figs. 15 to is employed a at its forward by a disk 152. The rear 19, inclusive. In this form there tubular casing 151 reduced end of the casing is enlarged and the enlarged portion is sub-' divided by two partitions 153 and 154.

Passing through the end disk or. plate 152 and having a rotary bearing therein,.-.is a spindle 155, to the outer end of which is at.- tached a ring 156. A shoulder on the spindle limits the inward movement of the latter,

anda hollow drum 159 is threaded on to the spindle upon the inside of the casing to limit the outward movement of said spindle.

The rear surface of the drum 159'is provided with ratchet teeth 161 having engage- -ment with a pawl 162 pivotally mounted on the disk or end wall 152. Rotatably mounted on the inner end of the spindle 155 is a sleeve 163, which also has a rotary bearing in the partition 154. The sleeve 163 carries an internal gear wheel 164, concentric with details of construction illustrated in' endand closed at its rear end and adjacent to an internal gear wheel 165 7 carried at the outer edge of a flange on the drum 159. The sleeve 163 extends through the partition 154 and is provided with a gear wheel 166. A shaft-.167 is mounted in the two partitions and is provided with two pinions 168 and-169, the former of which meshes with the internal gear 164. A second shaft 170 is mounted in the two partitions and has two pinions 171 .and 172, the former of which meshes with the gear 166.

Rotatably mounted in the partition 153,

and in the SIGBWE 163 is a shaft 17 3 having a mesh either with the pinion 169 or with the inion 172. The partition 153 has a hub 1 5, upon which there is rotatably mounted an inner-casing 176 polygonal in cross section. lhis casing has an end plate 177 bearing directly on said hub and provided with an internal gear 178 closely adjacent the partition. '1! .sleeve 180 has bearing in the partition and at one end is provided with a pinion 179 in mesh with the internal gear 178., A slip clutch collar 181 is keyed to the sleeve 180, so as each other. Upon this shaft is a pinion 184 in mesh with the internal gear 165 and slidably but not rotatably mounted on the shaft is a slip clutch collar 185 normally pressed toward the other slip collar by a suitable spring.

The shaft 173 is provided intermediate its ends with a universal joint 188, and at the outer end of the outer section is a brush 189.

The brush is preferably detachably secured so that it may be replaced by one of a different character and said brush is preferably held against rotation in respect to the shaft by a key 190. A hood 192 incloses a portion of the brush so as to leave only a part of the periphery of the latter exposed, and the hood is preferably slidably connected to the reduced end of the main casing. The outer end of the hood constitutes a bearing for the shaft and is preferably provided with an elongated slot 195 to permit of a limited movement of the shaft upon the joint 188. Within the reduced portion of the casing and extending to the periphery of the brush within the hood, is a curved dove-tailed channel 194, through which the material to be used in connection with the brush is delive'red. At the terminal a portion of the channel the sides are cut away to form a cage or grating having a series of slots 196,

through which the periphery of the brush may pass. The tablets in passing along the channel to the end thereof stop adjacent the .brush, where each tablet in succession is slowly Worn awav by the rubbing action of the brush. Small projections 197 on the channel serve'to prevent the brush from unduly spreading beyond the sides of the cage or grating.

It will be seen, by referring to Fig. 19, which shows an end view of the hood 192,

that the lower part of the slot 195'is square to receive a quadrangular section formed on one end of the round shaft 173. "The shaft 173 is firmly held in engagement with the square part of the slot 195 by the spring 122, so that a longitudinal movement of the hood 192, with respect to the tubular casing 151, must be communicated to the shaft 173.-

The shoulders formed on the shaft 173, by

the reduction of its squared end, form a positive engagement with the hood 192 during the latters movement to the right. 7

Within the casing and adjacent the beginning of the reduced portion, there is provided a partition 198, within which the shaft 173 has a hearing. A slot is cut in this of tablets rather than the shaving of shaft and lock it against rotation.

partition and the portion adjacent the slot is bent inwardly to form a guiding tongue 199, which is in alinement with the channel 191 and practically constitutes a portion thereof. Within the inner casing 176 is a container '200, polygonal in cross section and held 203. Within the container 200 are placed the tablets, and as the container rotates in respectto' the partition 198 and channel 194, the tablets are guided out through into the channel and delivered to the vicinity of the brush.

The operation of the device shown in Figs. 15 to 19, inclusive, is somewhat similar to that of the device illustrated in Fig. 1, save that it is adapted for the delivering I a powder from a solid block of material. The motor is operated by a spring, not shown, one end of the spring being secured to the sleeve 163 and the other end of the spring being secured to the inner surface of the drum 161. The spring is wound by turning the ring l56 inrespect to the casing. Turn- 'ing.of the drum is permitted bythe slipping .of the clutch members 185 and 181.

This gives the shaft 173, the casing and the container, a rotation in one direction.

In case, it is desired to rotate the brush and its connected parts in the opposite. direction, the hood 192 is moved longitudinally in respect "to the casing and the shaft 173 is moved inwardly to move the gear 174 constructed as to grip the square end of the Thus, the motor and brush are automatically stopped as soon as the brush is removed from the surface being treated, as the weight of the brush or a small spring 122 presses it away from the tablets and brings the end of the shaft into the lower reduced end of the slot 195.
